How are Merlin-Cards handeld when a quest is solved?
Is there a rule in which order Merlin-Cards habe to be evaluated?

Following happend:
Merlin #5 and Merlin #3 (disk for the dragon-quest) is in play.
The dragon-quest has to be solved - exact 5 cards are in the pile.

Is the quest solved immediatly a won, as Merlin #5 tells, that a quest is won, when exact 5 cards of the quest are in the pile?
Or must first Merlin #3 be used, because than the quest must be solved as a normal quest, beacause there are only 4 cards left?
